I am somewhat perplexed as to how pulsed electromagnetic therapy would be capable of removing spurs and calcific growths? Most wavelengths operate between 1850 angstroms and 150 kilometers. If you were engaged in using it in Grenz ray or radium therapy I would be concerned for any application of any unknown metabolic disease process such as tumors. All it is is s form of heat which will cause vasoldialation. Yes, it will increase phagocytosis but it can have no property for the elimination of calcific deposition. Sounds like a ruse and I would be wary of such supportive testimonials of this nature, since testimonials do not require authenticity as research does.
